[1] In this research, we investigate the large-time solution behavior of a representative bioreactive transport model under the conditions that the mixing of two required substrates occurs only in the directions transverse to groundwater flow. The transport physics is governed by the commonly used advection-dispersion equations at a steady uniform flow field. The microbial population dynamics a...

Ice cover in an open channel can influence the flow structure, such as velocity, Reynolds stress and turbulence intensity. This study analyzes vertical distributions of intensity fully partially ice-covered channels by theoretical methods laboratory experiments. According to experimental data, profile longitudinal velocities follows approximately symmetry form. Different from flow, maximum valu...

The microbiological stabilization treatment of beer sometimes guarantees the absence microbiota. These treatments, however, are not usually done in craft beers. In this study, we have analyzed 38 beers from Spanish market and found that, 68% cases, exogenous microbiota is present. samples been classified based on their alcohol content results shown a large presence wild yeasts 100% contaminated...

Contaminant hydrology is the study of processes that affect both ground and surface water pollution. It draws on the principles of hydrology and chemistry. Contaminant hydrology and water quality research seeks to understand the role of soil properties and hydrologic processes on ground and surface water pollution and develop strategies to mitigate their impacts. Research is done at all scales ...
